this looks doable, but I would recommended forgetting the scissors and going with a rotary cutter (like we use in quilting) can buy at any big box or craft store for little $ and it comes in handy with SO many projects.

Although I wonder how well this would stand up to repeated washings, I guess it would mostly depend on the quality of the grid and how tightly you tied the strips.

This is really beautiful. I've thought about doing it with t-shirts for my sons nursery. I'm concerned about making a bathmat though. How can it be washed? Something like would get pretty dingy and gross rather quickly I would think.

Looks like it might leave a lot of little white bits all around. You can see when cutting and/or tying that it leaves little 'crumbs'... that could get messy? Anyone try this and know how much towel bits are left behind?
